Abstract

The magnetic field variation by the permanent magnet fluctuation positioned on a "Chwan" of wrist according to the movement of radial artery was generated. The clip-type pulsimeter equipped with a Hall device sensing magnetic field pulse movement analyzed the characteristics of pulse wave as output signals. The magnetic field curve and pulse waveform simulated by the finite element method were compared and analyzed with each other. Also, the variation of magnetic field distribution one permanent magnet investigated by the fabrication of clip-type pulsimeter simulator. This result suggests that the clip-type pulsimeter can be used the reproducible and efficacious oriental diagnostic medical instrument.

요골동맥의 움직임에 따라 손목의 "관" 위치에 놓인 영구자석이 요동함으로 자기장의 변화를 생성하였다. 맥동에 의존하는 자기장을 감지하는 홀소자가 구비된 집게형맥진기의 출력신호인 맥진파형 특성을 분석하였다. 유한요소법으로 전산모사한 자기장 파형과 실제 맥진 파형의 시간 특징점들은 거의 일치하였다. 한 개의 원통 소형 영구자석의 자기장 분포의 변화를 감지하는 홀소자 집게형맥진기 시뮬레이터를 제작하여 재현성과 유효성 있는 한방진단기기로 활용하는 기틀을 마련하였다.
